abc's of confined space safety
DESCRIPTION
An average of 92 workers are killed each year in confined space accidents. Magid Glove and Safety teamed up with MSA to create this presentation in effort to help reduce that number by informing you of these hazards and providing you simple solutions to better test your work environment.TRANSCRIPT

An average of 92 workers
are killed each year in
confined space accidents
“Rescuers” make up 60% of
confined space fatalities
Confined Space Dangers
Because every life has a purpose… © MSA 2012
Confined Space Hazards
Presence of toxic gases
Oxygen deficiency or enrichment
Potential for engulfment
Flammable gas above 10% LEL
Mechanical Devices
Physical Obstacles
Sloped floors which may pin &
cause asphyxiation
Any potential for IDLH
atmospheres

Hazardous Atmosphere
• An atmosphere that may pose a risk of death, incapacitation, impairment of the ability to self-rescue, or acute illness.
◘ Flammable gas, vapor or mist > 10% of LEL
◘ Oxygen < 19.5% or > 23.5%
◘ Airborne combustible dust that meets LFL
◘ Atmospheric concentration of substance in excess of OSHA PELs in Subpart G or Z
◘ Any other condition that is considered IDLH
Key Definitions
Because every life has a purpose… © MSA 2012
What is LEL?
Below Lower Explosive Limit - not enough fuel to ignite
Above Upper Explosive Limit - not enough oxygen
Between LEL and UEL -atmosphere is explosive
Because every life has a purpose… © MSA 2012
Need to sample at all levels in confined space
METHANE (Lighter Than Air)
CARBON MONOXIDE (Same Molecular Weight As Air)
HYDROGEN SULFIDE (Heavier Than Air)
Gases Have Different
“Molecular” Weights

Initial testing shall be completed with the ventilation systems shut down.
Further testing shall be conducted with ventilation turned on
Conducted in a manner that represents the atmosphere throughout the confined space
Atmospheric Testing

Instrument Reliability Verification
• Calibration shall be conducted according to the manufacturer’s recommendations
• At a minimum, a function check (e.g., bump test) shall be done prior to each days use.
• An instrument maintenance record shall be maintained.
Calibration and Bump Testing
Because every life has a purpose… © MSA 2012
Why use an Automated (GX2) Test System? • Ease of Use
◘ Fully automated making bump testing and calibration so easy, that anyone can do it
◘ Electronic cylinder holder allows customers to be up and running with no setup required
• Proactive Safety
◘ Track bump testing and calibrations for instrument fleet
◘ Download instrument data logs and send automatic emails when action is required
• Best Total Cost of Ownership
◘ Track gas usage, gas expiration, end of sensor life warnings, sensor replacements, and instrument history to reduce down-time and overall maintenance costs
◘ Optimized for use with Xcell sensors yielding fastest test times in the market!

XCell Sensor
Designed and built by MSA
• MSA IS Advancing Sensor Technology!
• Our sensors are designed for OUR instruments!
• We have the experts to support YOU!
Because every life has a purpose… © MSA 2012
XCell Ex Sensor
XCell Ex - Catalytic Combustible Sensor
• 4-Year Life, Fast Response, Very Durable
• Only industry sensor with two detector beads (Patent Pending)
◘ Only one bead active at a time – doubles working life of sensor
• Patent-Pending metal alloy support wire for increased
durability
• More poison resistance to silicones and sulfur compounds
• Fast T(90) response time, Typical < 10 sec CH4
Because every life has a purpose… © MSA 2012
XCell O2 Sensor
XCell O2 - Oxygen Sensor
• >4-Year Life, Fast Response, Very Durable
• Long life from patent-pending “Lead Free” sensor design
◘ Nothing is consumed in the chemical reaction
◘ Most other sensors die at 2-years when enough lead is converted
• Fast T(90) response time, Typical < 10 sec O2
Because every life has a purpose… © MSA 2012
MSA provides the best portable instrument solutions!
• Speed of response, advantages of faster alarming
◘ Humans average walking speed = 83m per min
◘ t90 avg response time of big 4
♦ Xcell Sensors = 10-15 sec (~20m into the CS)
♦ Industry avg = 25-30 sec (>40m into the CS)
♦ Action can be taken in half the time in potential life-threatening
situations!
• Best Total Cost of Ownership
◘ Longer Sensor Life
◘ Calibration Gas Flow Rate
We have the best gas detection instruments in the market!
• Reliable, durable and easy to use
Confined Space: Why
MSA is Simply the Best

Industry first LEL, O2, H2S, CO, SO2 bump and calibration using a single cylinder
• Bump test time 10 seconds
• Calibration time 60 seconds
Why are we first?
• XCell SO2 sensor T90 response time is 6 times faster than industry average
• Slower SO2 calibration times cause long exposures of H2S which will kill/poison the LEL sensor
Industry first Big 5
